From December 2020, on the basis of improving the efficiency and aesthetics of trash bins suggested by the Department of Natural Resources and Environment of Phu Yen to support the classification and resource of waste, the product of Plant organic waste into compost bin, made by a group of Mien Trung Industry and Trade College led by Dr. Vo Anh Khue has successfully been pilot implementation.

Domestic waste is divided into organic waste, inorganic waste and hazardous waste. Normally, households will classify waste into two categories as reusable and non-reusable. Waste that is not reused will be transported to the landfill. The result is pressure on the landfill, wasting resources, cost of transportation, potentially causing environmental pollution in the landfill, potentially causing accidents for workers, people living on landfill and many other dangers.
With the aim of contributing effectively to the classification and sesource of plant organic waste, the authors of the study designed a type of trash bin operating on the principle of anaerobic, the microorganisms that decompose the waste are mainly in the form of medium thermophilic aerobic microorganisms. The industrial design is different from the trash bins currently on the market. The compost can be incubated once or many times. The mechanism of mechanical mixing is convenient, does not use electricity, so it is safe, the bin is recycled from plastic containers, waste tires, so it has a great meaning in resource waste into useful products. And this useful product is used to resource plant waste into compost.
The improved organic compost bin is a research result led by Dr. Vo Anh Khue, accepted by Mien Trung Industry and Trade College, and recognized for the school-level initiative in 2021. The index of the organic composting process achieved good results (the main feature is high temperature. stable, no odors, incubation time 2 months) through real model.
Using compost bin at households is a useful solution to help protect the environment, recycle organic waste on site into compost, reduce transportation, collection, treatment costs and save land used for landfill garbage. This trash bin combined with the bio-cleaning water production process will contribute to the classification and thorough treatment of plant waste in the household effectively.
